Abstract

L'invention concerne un système de mesure en temps réel du débit instantané d'un fluide en écoulement stationnaire ou instationnaire dans une conduite, comprenant un organe d'écoulement (1) du fluide muni d'au moins deux prises de pression (A, B) en paroi, un moyen de mesure (2) d'une différence de pression couplé aux deux prises de pression (A, B), et un moyen de calcul (3) pour calculer le débit en temps réel par la résolution d'une équation différentielle ordinaire non-linéaire reliant le débit instantané à la différence de pression, la différence de pression dans ladite formule étant positive ou négative en fonction de la variation de la vitesse d'écoulement du fluide dans la conduite et/ou du sens de l'écoulement du fluide, caractérisé en ce que l'organe d'écoulement (1) comprend un filtre (4) placé entre les deux prises de pression (A, B) pour augmenter la perte de charge.
